Very nice, thank you for the feedback.
I can't see on your pics the paint cracks, so i guess that's good.
Having looked at Aliexpress recently, some sellers explain the VAT shenanigans to Europe. If i got it right, the price you see when shopping includes VAT by law, but when you checkout you dont pay it (I think the deal is that above a certain amount (i think 100 or 150 EUR), the VAT isn't forcibly charged). Then shipping is shipping.

How does the bike compare to your previous bike, how does it ride, are you happy?

It looks like tantan is listing the weight as ~1100g while seraph is listing it as 1300g. Could one of you weigh it when you get it? This is definitely the top of my list right now.

Easiest is probably to ask them. I think (I may be confusing manufacturers, so bear with me) they sometimes offer 2 carbon layups, the light version i've seen requiring a MOQ of 10 or more.
So it could be the same frame / mould with different layups.

I've mentioned this multiple times in the other thread, 32mm wide is not going to cut it on this frame.

I was very excited to find this as I thought it was a perfect fit, but the tire clearance was a dealbreaker for me. Ended up selling it, I loved it otherwise!

Sorry, on which frame are you referring to? This is the FM025.
The X37 is marketed as 35C, and they say they dont have stock, it's brand new.

Tantan website actually says that max is 35c http://www.tantancycling.com/index.php?_m=mod_product&_a=view&p_id=1084 I guess?

From the photos it looks fine, I don't think there's a chance of rubbing and there's enough room for stuff and dirt. However, it is hard to say how wide the tyre actually is without knowing how wide are the wheels used in the picture

Haha, you're right, they changed it again! literally 5 days ago it said 30, then 32 last time i checked, then 35.
Well if they're now marketing it as 35C, and not even 35mm, any 32C tyre, even on a 32mm wide rim, should fit.

Hi all, i'm in the market for a Chinese road frame. I'd go with the VB 177 if it could handle 32C tyres comfortably, but it seems it can't.
I contacted Tantan, they sent me these pictures of their FM025 frame. The page used to say 30C max until a few days ago, they made the change because of the questions I asked. So now it says 32C max. These pics are with a conti 5000 32C tyre.
I'm not a power sprinter so i dont expect to flex my frame like mad, but does it look like the frame can comfortably handle 32C? It' a very important point for me, i've tested 28 and 32 back to back and the comfort difference is material, yet Peak Torque has shown there is virtually no performance downside providing you use a super wide rim. So my next road bike must accommodate 32C.
Thanks!

EDIT NOTE: I asked them for X37, they said no stock, so they're suggesting FM025 instead. That one used to say 30C, they then changed the description to 32C. The X37 has been 35C the whole time, which is why i contacted them in the 1st place. Apologies i got the models confused. So these photos are FM025.

Hard to tell apart from the VB GF002. I've built and ridden 2 of these, flawless.
Happy riding

Such a bummer that it doesnt take 32C tyres. It looks like a factor ostro, which takes 32C easily.

non integrated + stiff + narrow + cheap, you have aluminum. Wont be aero though. But i have a lot of friends who refuse riding carbon handlebars.
On aero, alu 36 or 38cm will probably make the whole system (you + bike) more aero than an aero 40cm bar. I dont think the drag of non integrated handlebars, given you have exposed cables anyway, matters too much. It would probably matter quite a bit with an integrated cockpit & full cable integration.

474
Yes, I am running the housing all the way to the R7000 FD. The cable housing is pushing against the FD stopper (as illustrated in the image documentation in my above post and my attached image here).
This is exactly the same principle as the Rear Derailleur, but the Rear Derailleur has a tension adjuster but works with similar principle; the housing is pushed against the RD cable housing stopper.

You just need to make sure to remove all the slack from the Front Derailleur cable before you tight it down.
Don't think too much about it. Just try it. It works guys!

This only works with Front Derailleur with a built in cable stopper like the Shimano 105 R7000 front derailleur.

Excuse my dirty bike in the images.

Wow, this is awesome. It means that the hole in the frame barely matters anymore. I spent so much time tinkering with the FD on these 4 bikes. Had i known, i'd have used your trick right away, and bought 4 of these 105 R7000 FDs. Also, apparently (as per some YT video), the SPCycle SP-053D has a weird FD hole, so your technique may also help that frame.

Bottom line, thank you, and you may consider posting a dedicated thread on your FD hack, because i believe that a LOT of people on this forum are having issues with setting up their mechanical FD when they get their new chinese frame.

I attached the price table for wheels from Lightcarbon too.
Does anyone here have experience with?

I have ordered 7 sets from Farsports over the years. I would suggest you speak with them, I think they're cheaper, and really doubt they're any worse. I've ridden their wheels in many situations where i'd straight up die if anything went wrong. They have been making great wheels for many years :)

Will this frame clear 32c Panaracer GKs or GK SS?

Various comments on the forum saying 32C on the 177 is very sketchy. Which is a major bummer for me. I want to run 32C Conti 5000 on 32mm wide rims on my next road bike. I've ridden 28 and 32mm back to back, difference is very material, yet peak torque showed on YT there's no penalty using 32C, either rolling resistance or CDA, proving you're running wide rims (32mm)

477
Well, as title suggests, I'm right now between two wheelset, carbon spoke wheelset but with rim (nipple) holes vs standard Saphim CX Ray but without rim holes, so which one do you think should be stiffer and more responsive?

Carbon spokes will be much stiffer. And presumably, responsive.
My wheels use sapim cx ray, because i'm 80kg, i like comfort, and i'm the limiting factor, not my gear.
Bear in mind that carbon spokes are much more likely to break, changing them may be an adventure, and so on.

For the 105 R7000 mechanical front derailleur, what works for me with these frames is running the cable housing all the way to the FD's cable stopper (see attached image for reference). Then I use any of these clips from Amazon or AliExpress for the cable housing/frame body interface.
I use the 105 R7000 FD for all my mechanical build no matter the RD or crankset. Cheap and very easy for me to work with.

Hi, do you have pics of actual builds? Very curious about your method, because i've built 4 chinese frames recently, and the FD has been far the biggest issue every time. I thought the housing had to push against the frame, then comes the cable. But it sounds you're running the housing all the way to the FD.
Please enlighten us, i think a lot of people are having issues with their FDs
Thanks!

Current build plan is:
-standard Seka frameset+bar+Token BB (1054gr frame, 370gr fork, 325gr bar, 165gr post, 105gr BB)
-LTWOO R9 Disc carbon (11-speed) groupset (1167gr brifters+derraileurs+calipers, 200gr cables+housing)
-Magene P325CS powermeter crank (730gr)
-YBN SLA-110 chain (249gr)
-SROAD one-piece CNC cassette (230gr)
-|||PRO brand rotors (308gr)
-ICAN Aero 35 disc wheels (1355gr)
-GP5000s tires (280gr x2)
-Specialized power S-works carbon saddle (160gr)
-No-name Supacaz imitation handlebar tape (50gr)

According to my calculations given quoted weights for everything is estimated at 7100 grams. We'll see about that! I'm guessing going from a M to a L will add ~200g+, and the accumulated error on quoted weights will add up to over ~300gr, so I would be very happy if it was anywhere close to 7.5kg dry.


You're probably missing thru axles (not trivial), headset bearings & compression plug (measured mine at 122g) either tubes (80x2 for latex, 30x2 for TPU) or sealant (100+x2), maybe tyre insert, tubeless valves. Not all frame sellers include headset bearings & thru axles. Wheel sellers typically dont include thru axles.

Im running 25’s. I got PLENTY of room. Probably could run 32’s comfortably, but i have no desire to find out as its a road bike.

Having ridden back to back Conti 5000 28 and 32 on similar spec wheels, i'd say, don't dismiss 32C. Peak Torque has tested that assuming your rims are extra wide (32mm, presumably), there's no aero penalty, and no rolling resistance penalty to running 32.
The difference in comfort is so stark that i'm looking for a road bike that can comfortably run 32C.

How's the bike been holding up? I like the design, Trek is one of the rare brands that's not making "everybody else's frame".
